Uncle Sam-I Want You Dead (1997)

After being killed by friendly fire during the Gulf War, soldier Sam Harper (David Shark Fralick) inexplicably returns from the dead to wreak revenge upon corrupt military men, draft dodgers, tax cheats, and flag burners. His memory is cherished only by his nephew, who doesn't realize that in life Sam was an angry, violent alcoholic who abused his family members and earned his heroic medals simply by being psychotic on the battlefield. Sam crawls out of his coffin after being brought back to his hometown, steals an Uncle Sam costume and proceeds to wreak havoc on insincere patriots during a Fourth of July celebration.
